I'm rooting for my home country of course: Belgium.
We're already glad we finally made it again to the finals, however with the quality we have now and the group we are in, making it to the 16th finals is a must, no excuses. We have got the 6th most expensive team present on the WC, so not being able to finish 1st or 2nd in our group would be the same as Spain, Germany or Brasil failing to qualify for the knock-out stages.
We aren't cocky enough though to proclaim ourselves as a potential champion, however we don't have to fear any team either. We could be considered a very dark horse, but the same applies to Chile, Colombia and Japan who all brought some high-quality teams.
